'Little Couple' star Jen Arnold shares cancer update

Earlier this month we shared the unfortunate news that the star of TLC's "The Little Couple," Jen Arnold, revealed she has stage 3 choriocarcinoma, a rare type of cancer.

The reality TV personality gave fans an update of her ongoing battle via a Twitter photo she shared Friday.

Arnold snapped the pic during her second day of inpatient chemo therapy. She recently said the visit was originally scheduled for last week but was cancelled when doctors discovered she had a low blood count.
